Abstract
A thin steel plate mould for pouring coils comprises a seat, an internal mould, an external mould, an outlet plate and a pressure plate, wherein the external mould, the internal mould and the seat are compressed by the above pressure plate, and the outlet plate is connected with the external mould. The thin steel plate mould for pouring coils is characterized by welding a limit plate on the upper portion of the internal mould and arranging at least one arc and circular hole feeder head on the limit plate. The thin steel plate mould for pouring coils has the advantages that (1) the tightness among the seat, the internal mould and the external mould is significantly increased, (2) designs of a reinforcement ring and a taper on the internal mould are favorable for increasing mechanical intensity and withdrawing pattern effect of moulds, (3) design of a sealing strip guarantees avoiding leakage when pouring a coil, (4) the coil height required by the process without mechanical process is realized by the arrangement of the limit plate at the upper end of the mould, (5) the thin steel plate mould not only can be used for pouring a coil of a resin adding with stuffing system but used for pouring a coil of a resin without adding stuffing systems, and operation of withdrawing pattern is simple, (6) compared with the thick steel plate mould, the cost is reduced about two thirds.
